A hoodless down top, this time with a 650 fill down, should make the Beartooth one of the warmest jackets out there. In practice, this warmth is not noticeably greater than others. The face-fabric feels a little heavier than some, although it adds negligible amounts of weight when worn and did seem to prevent feathers from penetrating through the fabric too much. All the external pockets have zips, which adds to the bulk of the Beartooth when it’s packed, but does make it the jacket more useful for general use, even if the asymmetric baffles make it look like a shirt with the wrong buttons done up. This is one of the few jackets that doesn’t stuff into a pocket, instead cramming into an included stuff-sack. When worn, the soft collar lining reduces chafing and the same lining has been used inside the handwarmer pockets to keep your hands toasty.
